How Long Will Automatic Watering Device Work

Question From: Crestview, Florida, United States
Q: Yes i have 2 plants and 1 dripper per plant, set on 40 days. However i will be gone about 75 days will it last that long?

A: I can't answer that Heath. There are too many variables. Plant size, container size, water pressure, temperature, location and on and on. I suggest you have a friend or hire someone to reset the gizmo. Best And Happy Yardening, Nancy.
